Crouching, facing forward, with all its limbs drawn in, ringed markings on its back probably contrived with ukibori, the eyes inlaid in dark material.Signed beneath: Kozan. Although worn, the markings on the back are interesting, probably produced with a metal punch. It is possible that some of the circular rings were in raised relief using the ukibori technique.
